[edit] Oops! I deleted some files! Can I get them back?

• Files saved on the CVL machines are backed up nightly. You can recover any file deleted up to 31 days prior.

[edit] How to Retrieve Lost Data

1. Log into the CVL machines.

2. Look for the directory called "/backup".

3. Look for the directory with the date in the name.

• The date reflects when that particular snap shot of the files was taken.

4. Look under that directory and find a directory called "home" .

5. Look under that directory where you will find your home directory (named with your login name) and all of your files as of that date.

(fg.1) The "/backup" directory.

(fg.2) The "/backup/Backup.03.Sun_25_Mar_2007_05:07/home directory.

[edit] Still Having Issues?

• Here's an example:

• Suppose today is March 28, and three days ago you deleted a file.

1. First, login.

2. Go to the backup directory.

• To go to the backup directory type cd / backup .

3. Once in the backup directory type ls .

4. See figure 1.

• Three days back would be March 25.

5. Go to the backup called: Backup.03.Sun_25_Mar_2007_05:07.

6. See figure 2.

Note: Remember, we have tab completion for long file names.

• Rather than type out the long name of the directory, just type cd B<TAB>.
• This completes the name as far as it can: cd Backup.

7. Type the 03 for the third backup and type the tab button again.

• The computer will finish typing the long name for you: cd Backup.03.Sun_25_Mar_2007_05:07

8. Once in the directory Type: cd Home

9. Go to your files.

10. Type: cd <login_name> .

11. Type ls.

• You will see your files in the same state that they were when the backup was done.

12. Find your file.

13. Copy it to your home directory.

• The easist way to do this is type something like cp <file> /home/<login_name>.
